Turn-on valves HE
Classic
The Festo HE series turn-on valves switch the compressed air supply to a system safely and without pressure surges. The range covers 13 variants in port sizes G 1/8 to G 1 (MINI, MIDI, MAXI) and allows manual activation without delay while throttling pressure build-up. This prevents uncontrolled pressure peaks when pneumatic systems start up.
Port sizes G 1/8 to G 1 - MINI (1/8, 1/4, 3/8), MIDI (3/8, 1/2, 3/4), MAXI (3/4, 1, 1/2)
Throttled pressure build-up - protects downstream consumers from pressure peaks on switch-on
Manual handwheel - simple actuation without auxiliary energy, D variant available without cable connection
Classic compatibility - direct mounting to LF filters and LR regulators from the Classic range

Typical applications: Safe activation of compressed air distribution in production plants, protection of cylinders and valve terminals on system start-up, use as main shut-off in modular maintenance units, and as safety shut-off following emergency stops in mechanical engineering applications.
